dc.description.abstract An experimental analysis of Floyd–Steinberg and clustered dot halftones printed with both cyan and black toner on both 300 dpi and 600 dpi laser electrophotographic printers. The printed halftone ramps were measured as reflectance, R, versus coverage of toner, C in units of mass/area. Gravimetric analysis was used to measure coverage. Rather than modeling tone reproduction as a bilevel model of discrete dots on paper, the images were modeled as contiguous layers of colorant on paper. Both the Beer–Lambert and Kubelka–Munk laws were applied. Just as ideal bilevel halftone models require significant modifications to fit experimental data, so too were modifications of the continuous tone model required. The ideal continuous tone model tended to over-compensate for the traditional halftone corrections called “dot-gain”. Thus, the corrections applied to the continuous tone model were called ink “anti-gain” to emphasize the analogy with bilevel models. The resulting corrections resulted in reasonably good agreement between the model and the data. Moreover, exploring some of the characteristics of the model indicated a reasonable physical interpretation of the corrections that were applied. en_US
